PR 83087
On an OS6800/OS9000, the MAC aging time can take up to twice the configured value.
Workaround: There is no known workaround at this time.
PR 94127
On an OS9000, in the Hardware learning mode, the source MACs from control packets (BPDUs) are learned.
Workaround: There is no known workaround at this time.
PR 94180
On an OS9000, in the default learning mode, a MAC address will still be learned as a “bridging” entry instead of the “filtering” entry when it matches the QoS Drop rules. However, the actual packet is being discarded so the operation is functional.
Workaround: The switch could be configured to use “software” learning mode.
PR 94181
On an OS9000, if a QoS rule is set on a port to drop all traffic and if LPS is configured on the same port, no MACs are learned as part of LPS, as all the traffic is dropped.
Workaround: There is no known workaround at this time.
PR 94515
On an OS9000, on the port which has learned port security enabled, the first packet is not forwarded. Once this packet is validated, subsequent packets are forwarded without any problem.
Workaround: There is no known workaround at this time.
PR 94646
On an OS9000, the MAC address of an untagged packet does not get learned in the default VLAN with "filtering" and with "accept only" tagged frames.
Workaround: There is no known workaround at this time.
